From How I Met Your Mother producer Rob Greenberg, the single-camera comedy revolves around Carter, a young guy who finds camaraderie living among the more experienced guys he meets in a short-term rental complex. Paranormal Activity 3's Chris Smith will play Carter.

Penn will play Gil, a guy who moves into the complex as he awaits his wife's forgiveness following the world's worst affair -- three years ago.

Eric and Kim Tannenbaum are aboard to executive produce the project, which marks the network's first pilot order of the 2013-14 development season. Greenberg (Bent, Happy Endings) will write and direct the CBS TV Studios/Tannenbaum Co. pilot.

Penn, whose small-screen work also includes House and 24, is repped by Gersh, Industry Entertainment and Fuller Downs. He most recently completed ABC's pilot Prairie Dogs, which the network passed on in May.
